1 '0 all whom it may concern:

Be it known that I, Trroirms F. FEHRLE, a citizen of the United Eitates,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inHoppers, of which the following is a specification.

My invention relates to improvements in hoppers and particularly relatesto hoppers to be used in connection with machinery for treating wool.

The object of my. invention is to construct a hopper through which agreater amount of material may be passed, within a given time thanheretofore by reason. of its improved construction; a further object ofmy invention is to construct a hopper having the air inlet and theconveyer outlet apertures formed within the converging walls of thehopper, and thus dispensing with the usual form of vertical throat belowthe converging walls of the hopper. which throat tends to clog thehopper; and a still further object of my invention is to admit the airblast from the air supply pipe directly into the angular portion. of thehopper so that the air blast can keep the wool in the hopper agitatedand force it through the hopper with greater speed than is possible whenthe hopper is constructed with a throat portion between the hopperproper and the discharge opening of the conveyor pipe. By my improved.construction of the hopper economy of space is obtained, as a low-downtype of hopper thus provided, which may be used in connection with amachine having the discharge opening close to the floor level.

Referring to the accompanyingdrawings; Figure 1, is a perspective viewof my improved hopper shown in use with a-wool drier; Fig. 2, is a planview of the hopper; Fig. 3, is a side view of the hopper, partially insection; and Fig. 1, is an end view of the hopper.

in the accompanying drawings in which like reference characters refer tolike parts, the hopper 1, consists of the sloping side walls 2 and 3 andthe end walls 4: and 5. The converging walls of the hopper form aninverted truncated pyramid. The side walls 2 and 3 of the hopper, arecontinuous and form a curved bottom portion 6, connecting the side walls2 and 3.

The walls of the hopper are constructed of sheet metal and arereinforced by a rec= tangular top frame 7, formed of angle-iron,

and also by the supporting members 8, also of angle-iron. The supportingmembers 8 are substantially U-shaped, as shown in the end view Fig. 4,having a lower base portion 9 and side portions 10, which latter embracethe side walls of the hopper and are conings formed therein atthe placeswhere the pipes 12 and 13 are attached thereto and the said openingsformed in the end. walls are located between the apex and the base ofthe polyhedral angle.

The bottom portion 6 of the hopper is on the same level with the lowerportion of the pipes 12 and 13 and thus forms a continuous bottomsurface between the inlet pipe 12 and the outlet pipe 13.

The air as it is forced through the inlet pipe 12 strikes the deflectorplate 15, and is directed toward the bottom portion of the hopper andcarries the wool from the hopper into the outlet conveyor pipe 13.

By this construction of the hopper an excess accumulation of wool in thehopper will not clog the mouth of the outlet pipe 13, as the flaringwalls of the hopper permit the mass of material to expand as it islifted by the air from the inlet pipe 12.

in Fig. 1, the hopper is shown located at the discharge outlet of a wooldrier 20 in which the wool is dried by being conveyed through the drierupon the conveyer tables 21, in the usual manner.

Having thus described my invention I claim and desire to secure byLetters Patent:

1. A hopper comprising flaring walls, a bottom portion connecting theflaring walls, an outlet conveyor pipe connected with the hopper abovethe apex of the angle formed by the said walls of the hopper, an airinlet pipe connected with the hopper, a de flector plate located withinthe inlet pipe adjacent to the end thereof attached to the hopper, andsaid deflector plate inclined at an angle to direct the air toward thebottom of the inlet pipe and the bottom of the hopper.

2. A hopper comprising flaring side walls, a curved bottom portionconnecting the side walls, flaring end walls connected with the saidside Walls, said end Walls extending to the said bottom portlon andhavmgopenlngs 7 formed therein, horizontal pipes having angular Initered endscorresponding to the angle of the end walls and connected with the endwalls, said pipes registering With .the said openings formed in the endWalls,

said pipes located on the same level with hopperi the bottom portion ofthe hopper, and reinforcing frame members attached to the 10 MARTHA H;QUINN.
